What is the definition of population in ecology?
Organisms of the same kind living in the same place at the same time
The number of individuals of a species in the same place at the same time
The number of individuals per unit of area
The distribution of individuals within a habitat
What is population density?
The number of individuals of a species in the same place at the same time
The distribution of individuals within a habitat
The number of individuals per unit of area
The age structure of a population
What is the carrying capacity of a population?
The maximum number of offspring that an individual can produce
The number of individuals that leave a population
The number of individuals that die within a population
The largest number of individuals that can be supported without harm to the given individual and its environment
What is the difference between r-strategists and K-strategists?
r-strategists produce many offspring with little parental care, while K-strategists produce few offspring with extensive parental care
r-strategists produce few offspring with extensive parental care, while K-strategists produce many offspring with little parental care
r-strategists produce many offspring with extensive parental care, while K-strategists produce few offspring with little parental care
r-strategists produce few offspring with little parental care, while K-strategists produce many offspring with extensive parental care
What is the difference between primary succession and secondary succession?
Primary succession occurs when an established ecosystem is disturbed, while secondary succession occurs when new land is formed
Primary succession occurs when new land is formed, while secondary succession occurs when an established ecosystem is disturbed
Primary succession occurs when an ecosystem undergoes gradual change, while secondary succession occurs when an ecosystem undergoes catastrophic change
Primary succession occurs when an ecosystem undergoes catastrophic change, while secondary succession occurs when an ecosystem undergoes gradual change
What is a survivorship curve?
A graph of the number of individuals surviving at each age structure interval versus time
A graph of the number of individuals per unit of area versus time
A graph of the distribution of individuals within a habitat at a particular point in time
A graph of the population size over time
What is density-dependent population control?
Environmental factors that curtail biotic potential
Environmental factors that do not depend on the number of individuals in a population
Factors that increase population size
Factors that decrease population size
What is density-independent population control?
Environmental factors that curtail biotic potential
Environmental factors that do not depend on the number of individuals in a population
Factors that increase population size
Factors that decrease population size
What is a disturbance in an ecosystem?
Any significant change to the interactions in an ecosystem
A change that takes place over a short period of time
A change that takes place over a long period of time
The response of an ecosystem to change
What is inertia in relation to ecosystems?
The way an ecosystem responds to change
The ability of an ecosystem to resist change
The rate at which an ecosystem undergoes change
The stability of an ecosystem
